  3. Smart Contracts are written in Solidity and then compiled into byte code to be read by the EVM.

  4. Bitcoin using a more basic programming language (Script) which is not Turing Complete.

  5. A turing complete programming language is one which allows the use of loops (code that is executed repeatedly) and is capable of creating a program which can do virtually anything.

  1. The EVM is a “application” that runs in all Ethereum nodes that run the bytecode of smart contracts and verify through consensus that what is being executed by the code is true to the programmer’s intent.
    2.The EVM reads bytecode which is compiled from Solidity or, in the future, Viper
  2. Solidity is compiled to become executable bytecode. We need solidity because it would be very difficult to have to write bytecode
  3. Because it does not have loops and is thus not “Turing Complete”
    5.Solidity, C++, Python, and most other programming languages.

  1. What does the EVM do?
    It analyses the byte code in the smart contract and instructs the CPU node to begin executing its terms

  2. What is the format of the instructions that the EVM can read?
    Solidity compiler

  3. What is the relationship between the programming language Solidity and Bytecode?
    The Solidity compiler allows for any type of instruction to be coded into it. it takes this code and gathers/assembles these smart contract instructions into bytecode for the EVM to analyze and interpret.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can? Bitcoins programming language is limited. it was not designed for smart contracts. As such, there is a limitation on the range of coded instructions that can be created.

  5. What is a Turing Complete programming language? a type of language that enables the coder to create looping instructions, meaning that once a series of functions are performed, the program “loops” back and performs the same set of instructions again.

  • Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Because it is not turing complete

  • What is a Turing Complete programming language?
    It is a language that allows you to write every possible function, and also allows to tun loops to repeat the same action over and over.

  1. What does the EVM do?

EVM enables us to run Smart contracts on the Ethereum blockchain. EVM also ensures nothing malicious happens to the computer running the smart contract.

  1. What is the format of the instructions that the EVM can read?

EVM can only read byte code.

  1. What is the relationship between the programming language Solidity and Bytecode?

Smart contracts are written in Solidity. Then the compiler converts it to byte code. Then the byte code is read and executed by the EVM.

  1. Why can’t Bitcoin run the same type of complex programs like Ethereum can?

Bitcoin cannot run the same type of complex programs like Ethereum because Ethereum is a Turing complete language while bitcoin is not a Turing complete language.

  1. What is a Turing Complete programming language?

A programing language is said to be a Turing complete programing language if it can run an infinite number of loops.

EVM helpl CPU to execute code on the Eth network.

EVM is like a capsule that keep the Smart Contract instructions from leaking out into your CPU and it also protect the Smart Contracts info from being seen from the outer world.

The relationship between Solidity and Bytecode is that Solidity will compile all the info and the compiler will break the instructions down into Bytecode.

BTC run on a program called Script. Script is whats called (Not Turing) because it’s very limited on what it can do.

A Turing Complete (TC) programming language is a language that’s Eth currently run on. TC is programability , scripting and it gives developers the ability to build whatever they want.

  1. What does the EVM do?
    The EVM safely runs the code of Ethereum smart contracts.

  2. What is the format of the instructions that the EVM can read?
    The compiled code that the EVM runs is referred to as byte code.

  3. What is the relationship between the programming language Solidity and Bytecode?
    Programs written in solidity are compiled into Bytecode.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin’s script is very limited in what it able to do, it is not Turing complete.

  5. What is a Turing Complete programming language?
    The formal definition is a bit complicated but for the important features of Turing Completenssthat apply to a imperative language such as Solidity are:
    a. Some kind of conditional branching and repetition
    b. Some ability to read and write to some storage
    These are some of the most useful basic features that make most give modern programming languages their power.

  1. What does the EVM do?

During execution, the EVM maintains a transient memory as a word-addressed byte array, which does not persist between transactions. Contracts, however, do contain a Merkle Patricia storage trie as a word-addressable word array, associated with the account in question and part of the global state.

  1. What is the format of the instructions that the EVM can read?

Bytecode

  1. What is the relationship between the programming language Solidity and Bytecode?

The programs written in solidity are compiled into Bytecode to make it readable to the EVM (Etheruim Virtual Machine).

  1. Why can’t Bitcoin run the same type of complex programs like Ethereum can?

The script in Bitcoin is very limited in what it able to do and it’s not Turing complete.

  1. What is a Turing Complete programming language?

It’s a programming language that runs on Ethereum and allow for complete control for the developers to do whatever they want to do.

  1. It acts as the middleman between the program and the CPU. It reads the bytecode and creates consensus on all nodes.
  2. Bytecode
  3. Solidity is the language used by the program which the compiler turns into bytecode for the EVM to read.

Solidity is compiled into bytecode

Why can’t Bitcoin run the same type of complex programs like Ethereum can?

because bitcoin’s script language is not turing complete while ethereum’s solidity is turing complete.

  1. EVM= Ethereum Virtual Machine. Makes it possible to execute code on the ethereum network/blockchain. It is used to process Smart Contracts and reach consensus. It works in conjunction with the node’s CPU.
  2. Bytecode
  3. EVM uses Solidity and a Compiler to read the Bytecode.
  4. Bitcoin’s Script’ cannot run the same type of complex programs like Ethereum because it is not Turing Complete.
  5. Turing Complete languages are able to program anything (unlike Bitcoin’s Script that is limited to single programs). Turing Complete language uses ‘loops’ - the ability to program something 1000 times without coding it 100 times.

  • What does the EVM do?
    Etherium Virtual Machine safe guards a CPU from malware. EVM reads instruction written in byte code and directs the CPU to perform it.

  • What is the format of the instructions that the EVM can read?
    The instruction is written in solidity and gets compiled down to (EVM) byte code.

  • What is the relationship between the programming language Solidity and Bytecode?
    Solidity is a written format of instructions that can be easily read, a program compiles this language into smaller information inputs (bytecode) that can be universally read by other programs such as EVM.

  • Why can’t Bitcoin run the same type of complex programs like Ethereum can?Bitcoin is not “turing” complete. It remains a store of wealth/currency, with minimal programming abilities. BTC runs simple contracts avoiding “spam”, whereas Etherium can perform complicated contracts and is “turing” complete.

  • What is a Turing Complete programming language?
    It can contend with commands that are repetitive via a feature in a programming language called loops, which saves time and effort.

  1. EVM is a powerful virtual stack embedded on each ethereum node, responsible for executing byte code in smart contracts. Each node runs an EVM instance which also helps the network reach consensus.
  2. Bytecode and Solidity
  3. Solidity is compiled into bytecode which the EVM then reads and then executes the contract accordingly
  4. Because script is not turing complete
  5. This means that this system is able to recognize or decide other data-manipulation rule sets. Turing completeness is used as a way to express the power of such a data-manipulation rule set. Virtually all programming languages today are Turing-complete
